SigC::slot() (obj)
-----------------------
slot() can be applied to a object method to form a Slot with a
profile equivelent to the method. At the same time an instance
of that object must be specified. The object must be derived
from SigC::Object.
Sample usage:
struct A: public SigC::Object
{
void foo(int,int);
} a;
Slot2<void,int,int> s=slot(a,&A::foo);
